WILLIAM A. ANDERSON, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-THIRD TO ROBERT BURNS, OF SAME PLACE.

SECTIONAL CANTEEN OR COFFEE-FLASK.

SPECIFICATION forming part of Letters Patent No. 475,231, dated May 17, 1892. Application filed November 18, 1891. Serial No. 412,347- (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. ANDERSON, a citizen of the United States, and a resident of the city of Chicago,in the county of Cook and State of Illinois, have invented a certain new and useful Improved Sectional Canteen or Cofiee-Flask, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

The present invention relates to pocketflasksor canteens, the purpose of the present improvement being to provide an improved sectional construction thereof, so as to afford ready and convenient access to the whole interior thereof for cleaning'purposes, and with.

which liability to leakage is avoided in a very perfect manner. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which-.-

Figure 1 is a perspective view of. the canteen parts in a detached condition; Fig. 2, a detail section of the jointbetween the sections.

Similar numerals of reference indicatelike parts in the difierent views.

As represented in the drawings, my improved flask or canteen will usually consist'of two sections 1 and 2, having the usual elliptical or other flattened form, each section being formed Witha top and bottom head, as shown, the top section being provided with the usual pouring neck 3, closed by a screwcap or other usual means. The two sections are connected together end to end, so that there will be a communication between their interior chambers by means of an annular screw-threaded joint surrounding the comm unicating orifices 4 and 5 in the respective heads of the sections, such joint being composed of an inturned screw threaded annular neck 6 on the head of the upper section 1 and an outturned screw-threaded annular neck 7 on the head of the lower section. The orifices 4 and 5-will be made comparatively large, so 5 as to admit of ready access to the interior of the sections in the operation of cleaning the same, and it is preferableto spin the screwthreaded necks 6 and 7 in the usual manner either in the metal of the section-heads or separate therefrom and secured thereto subsequently by solder.

\Nhile my improved flask or canteen will usually consist of two sections, as shown,it is evident that any required number may be assembled together, so as to afford a flask of any desired capacity.

I am aware that prior to myinvention bottles have been made in sections with the adjacent open ends con nected together by a mar- 6Q ginal screw-thread. I therefore make no claim to any such construction, broadly; but as a slight modification the line of division between sections when connected may have an oblique arrangement without departing from the spirit of my invention.

Having thus fully described my said invention, what I claim as new, and desire to secure .by Letters Patent, :is

1. A sectional flask or canteen comprising the flattened sections l and 2, having heads at each end and provided with annular necks 6 and 7 on the adjacent heads that are adapted to connect the two sections together, substantially as set forth.

2. A sectional flask or canteen comprising the flattened sections 1 and 2, having heads at each end and provided with annular screwthreaded necks 6 and 7 on the adjacent heads that are adapted to screw together to unite 8o p the two sections together,substantially as set forth.
